My invention relates to an improved Stenrwindmg and stem-setting watchof what I may term as the clutch type as distinguished from the rockingyoke type. the object being to convert a mechanism of the clutch-typefrom a pushin set to a pullout set, and thus secure for pull-out setsthe advantages of simplicity and reliability adhering to the clutch typeof mechanism.

\Vith these ends in view my invention consists in stem-winding andstem-setting watch having certain details of construction andcombinations of parts as will be hereinafter described and pointed outin the claims.

In carrying out my invention as herein shown, the lower clutch-member 10is formed with a. circumferential groove 11 receiving the inner end of asecondary setting-lever 12 pivotally mounted upon the movement pillar13. The said lever is formed with an operating-bevel 141, and alocking-notch 15 both coacting with the inner or lower arm 16 of aprimary settinglever 17 pivotally mounted upon a screw stud 18 in thefront movement-plate 19, the outer or upper arm 20 of the said leverentering a circumferential groove 21 in the lower end of alongitudinally movable and rotatable winding and setting stem 22 uponthe outer end of which the crown 23 is mounted. The said stem 22 isitself mounted in the watch-ease 46.

hen the crown 23 and stem 22 are pulled outward, the inner clutch-member10 will through the medium of the levers 12 and 17, be moved inward anddisconnected from its complementary outer clutch -member 24, while whenthe said crown and stem are pushed inward the inner clutch-member 10will through the said levers be moved outward and re-engaged with theouter clutchmember 241-.

\Vhen the crown 23 is pulled outward and the clutch members 10 and 24are disengaged as described, the setting pinion 25 is correspondinglvmoved inward from the position in which it is shown in Fig. 2, into theposition in which it is shown in Fig. 4, in which latter position itmeshes into the intermediate setting-wheel 26 which meshes into theminute-wheel 2'? of the dial-work. The said setting-pinion 25 is mountedupon the squared upper end of a longitudinally movable and rotatablewinding-and-setting shaft 28 the said squared outer end of which 'spring29 free to nect the clutch-members 10 and enters a square opening in theinner end of the winding-and-setting stem 22 with which the said shaftis arranged in line.

The inner clutch-member 1O aforesaid is non-rotatably mounted upon thesquare inner end of the shaft 28 which is directly rotated by therotation of the stem 22 and longitudinally moved inward by the longitudinal movement outward of the said stem acting through the levers 12and 17. The outward movement of the shaft 28 for the restoration of themechanism to its'normal or winding adjustment, is effected by a spring29 engaging with its extreme inner end.

The upper clutch-men'iber 2L aforesaid, is formed upon the inner orlower face of a winding-pinion 30 which is formed with an outwardlyextending sleeve 31 by means of which it is journaled in a bridge 32located at the bottom of notches 33 in the upper edges of themovement-plates 19 and 311. The said winding-pinion 25 is constantly inmesh with an intermediate winding-pinion 35 mounted in the barrel-bridge36. lVhen the said bridge 36 is in position the wheel 35 meshes intoteeth 37 upon the' main-spring barrel 38 which turns on the main-arbor39 carrying the main-wheel 40 of the time-train of the watch movement.The main-wheel 10 meshes into a pinion 41 mounted upon the center-arbor42 which also carries the center-wheel as. A spring-actuated pawl d4: ofordinary construction, coacts with the teeth 37 of the barrel 38 forpreventing the reverse rotation thereof.

In the normal position of my improved stem-winding and stem-settingmechanism, the winding-and-setting stem 22 is pushed inward, whereby theprimary setting-lever 17 is disengaged from the lockingnotch 15 in thesecondary setting-lever 12, leaving the push the winding-and-settingshaft 28 outward for the coupling of the inner and outer clutch members10 and 24 and for the demeshing of the settingpinion 25 from theintermediate settingpinion 26. The rotation of the crown 23 and hence ofthe stem 22, will now operate through the winding-pinion 30 to wind thewatch.

To set .the watch, the crown 23 is pulled outward, with the effect ofcrowding the arm 16 of the primary setting-lever 17 down upon the bevel1 1 of the secondary setting-lever 12 which is thus forced inwardagainst the tension of thespring 29 for a sufficient distance to pullthe shaft 28 inward enough to discon- 24 and to move the setting-pinion25 inward into position to mesh with the intermediate settingwheel 26.After the shaft 28 has been so moved, the end of the arm 16 of the lever17 snaps into the locking notch 15 in the lever 12 and locks the twolevers 12 and 17 in their setting positions in which they will remain,while the watch is being set, after which the coupling of the levers isbroken by pushing in upon the crown which causes the arm 10 of the lever17 to be thrown out of the locking-notch 15 in the setting lever 12.

The winding-and-setting stem carrying the crown 23, is mounted in thepcndantsl') of the watch-case t6, the said pendant being provided withthe usual bow 47. The winding and setting stem 22 may thus be said to beorganized with the ease, whereas the winding-and-setting shaft 28 isorganized with the watch-movenrent.

Under the construction shown and described, the shaft is pulled inwardand pushed outward by its inner end through the medium of the lovers 12and 17, whereas in the watches of the prior art corresponding shaftshave been pushed inward by the thrust upon the outer ends of thewatch-stems and pushed outward by springs, the positive operation of theshaft through its inner end being the characteristic feature of myinvention.

I claim 1. In a pull-out setting mechanism for stem-winding andstem-setting watches, the combination with a winding-and-setting stemorganized with the watch-case, of a windingand-setting shaft organizedwith the watchmovement and connected with the stem for rotation thereby,a primary setting-lever pivotally mounted upon the front movementplateand having its outer end connected with the said stem for positivemovement thereby inboth directions, a secondary setting-lever pivotallymounted upon the said front movement-plate and connected with the saidshaft for positively moving the same inward away from the said stem forconverting the watch from winding to setting, the said levers coactingdirectly with each other in being positively locked in their settingpositions, and means for moving the said shaft outward for convertingthe watch from setting to winding when the levers are unlocked.

2. In a pull-out setting mechanism for stem-winding and stem-settingwatches, the combination with a winding-and-setting stem organized withthe watch case, of a winding-and-setting shaft organized with thewatch-movement and connected with the said stem for rotation thereby, atwo-part clutch of which the upper member slides upon the said shaft,and the lower member is fastened thereto, a setting pinion upon the saidshaft for co-action with a member of the setting-train of the watch inthe inward position of the shaft, a primary setting-lever having itsouter end connected with the said stem for positive movement therewithin both directions, and a secondary settinglever connected with theinner end of the said shaft for positively moving the same inward todisconnect the inner member of the said clutch from the outer memberthereof and to bring the said pinion into position to function, andmeans for moving the said shaft outwardly to convert the watch fromsetting to Winding by moving the said pinion into its non-functioningposition and by reengaging the said clutch members.

8. In a pull-out setting mechanism for stenrwinding and stem-settingwatches, the combination with a winding-and-setting stem organized withthe watch case, of a winding-and-setting shaft organized with thewatch-movement, a setting pinion mounted upon the said shaft in positionto co-act with a member of the setting train of the watch when the shaftis moved inward for converting the watch from winding to setting, awinding pinion through which the said shaft passes, in which the shaftis free to slide and to rotate and which is constantly in mesh with amember of the winding-train of the watch, a two-part clutch mounted uponthe said shaft and co-acting with the said windingpinion, a primarysetting-lever connected with the said stem for positive operationthereby when the stem is moved in either direction, a secondarysetting-lever connected with the said two-part clutch for moving thesaid shaft inward to separate the parts of the clutch and thus convertthe watch from winding to setting, and to bring the setting-pinioncarried by the shaft into mesh with a member of the setting-train of thewatch.
